Dr. Arindam Das (PhD in Computer Science, York University, Toronto, Canada)

Welcome to my webpage!
                                                                                                                             
                                                                                                                                          

I am interested in the effects of learning.

Currently, I am investigating on how human learning impacts the performance of distributed systems that involve human interaction through graphical user interfaces.

Earlier, based on the ACT-R theory of human cognition, I had developed a computational model that provides insight into how much practice is needed by a human to progress from novice to expert level in learning a user interface layout. I had also developed a closed-form model that provides insight into how mentally effortful is it to learn a user interface layout relative to other user interface layouts. This closed-form model is an analytical approximation that is based on the declarative memory equations of ACT-R.

I obtained my PhD in Computer Science at York University, Toronto, Canada in October 2014. My doctoral research involved creation of cognitive models in the domain of Human-Computer Interaction. My doctoral dissertation advisor was Wolfgang Stuerzlinger. My external examiner was Frank E. Ritter. The title of my thesis was ACT-R Based Models For Learning Interactive Layouts. My PhD dissertation can be found here. I obtained my MSc in Computer Science at University of Windsor, Windsor, Canada in 1993. My MSc thesis advisor was Subir Bandyopadhyay. I obtained my bachelor degree, BTech (Honours) at Indian Institute of Technology, Kharagpur, India in 1991. After completing my MSc, I worked in the software industry for a while before starting my doctoral studies.
